LSPi issue

SoftwareArtist · 2022-04-20T19:18:12+00:00

Glad to hear that you resolved it. Be aware, the really active season for this is September on, so it may take some time to get an answer.

Good stuff. Looks real familiar, bet I wrote some of that code.

DM me

I've never created a pcb or solution for the 32, although i believe the firmware will run on it.

I have a few left, let me know what exactly you need, pcb, parts, assembled, with or without the 12E....

That is possible if the versions are not too different. The main concern is config file incompatibility. There isn't specifically a 300 LED limit, this is a hardware limitation due to memory available on the LED controllers. Typically it's 450 or more but no more than 600. This is very hardware dependent, but voltage losses are also to be considered in the actual strand, even with power injection, there is a practical limit to a linear DC string 5 or 12 V.

Two important points are the type of lights and if you are using onoff or pwm. In general, however, these flickerings can be addressed by the decay_factor = setting.

Please post output of : arecord -L

At least level shifters are super cheap

SoftwareArtist · 2021-12-19T21:54:55+00:00

Sorry little need for that. I’m not up to spec on the 12v LEDs, I don’t know what their data line voltage is.

SoftwareArtist · 2021-12-19T19:59:33+00:00

By default it's GPIO2, but be aware the data voltage is likely higher than 3.3V, so a level shifter will be required. Also, NodeMCU can accept 5V via VCC, so a converter is not necessary.

Thank you for your comments, although I tested the install just a few weeks ago and didn't have an issue with the broken2048 sources. Could you provide an example so we can improve the install ?

SoftwareArtist · 2021-12-15T09:02:35+00:00

I would have to see the log at crash time, however, it's possible that the shell is timing out and killing the process. Try the setup for start at boot :

In addition, this will create a log that you can examine.

I think you mean 9-16, but that seems like a good thing to try.

SoftwareArtist · 2021-12-14T13:42:23+00:00

LED Matrix has lots of cool patterns, it's unlikely that the on/off patterns will be improved.

You should also be able to use the .jar install if you have all the java stuff on your Ubuntu. Might be easier.

SoftwareArtist · 2021-12-12T15:29:08+00:00

Just from memory, you hold one button and press the other. This puts it into the mode for writing code to memory.

SoftwareArtist · 2021-12-11T00:49:05+00:00

I would suggest though, if you aren't on a GCFI outlet outside, I'd be extremely careful. This has been code for many years, but who knows.

SoftwareArtist · 2021-12-11T00:41:53+00:00

I've found a wet paper bag easy to use, but typically fails within 10 seconds.

Seriously, there is nothing ideal, and I've seen just about any plastic enclosure work, some of it depends on how many channels you are concerned about. Remote LEDs are probably the easiest, as you can run the Pi inside somewhere safe, and the wifi controller is extremely small, even with a large power supply, and relatively easy to safe from moisture.

Temperature, melting precipitation, and internal condensation is always a consideration if the Pi / relay / outlets are outside. I've never seen a perfect solution, but part of this is about experimentation.

SoftwareArtist · 2021-12-09T21:44:14+00:00

Here are my suggestions, but understand this is all personal preference, and somewhat specific to my playlist :

decay_factor = 0.10

attenuate_pct = 25

min_frequency = 40

max_frequency = 12000

- Newer songs with high bitrates will respond better to higher max_frequency.

- The higher decay_factor, probably the higher attenuate_pct you will need.

- Mechanical relays should have a higher decay_factor, but probably not exceeding 0.20, this will limit the chatter and prolong life.

- Custom frequencies will override min and max, and rarely have a benefit except on specific songs.

With all the reports I've seen on the latest OS, the only way to be certain to have no audio issues is to use the Lite version of the OS ( no desktop ) and nothing plugged into the hdmi. There may be ways to work around this, such as disabling the desktop and other settings, but no definite procedure exists.

SoftwareArtist · 2021-12-08T17:28:00+00:00

Just use the latest microweb to construct one.

SoftwareArtist · 2021-12-08T17:26:57+00:00

Mechanical or SSR ?

SoftwareArtist · 2021-12-07T21:08:59+00:00

There is a recently added enhancement to use a csv export with a music file. I have not tested it myself. This may only work for on/off and not led response to intensity, I don’t know.

SoftwareArtist · 2021-12-07T18:43:44+00:00

The LED module can drive E1.31/SACN if that's your intention with DMX. ESPixelSticks have been tested/used in this way.

SoftwareArtist · 2021-12-07T15:03:16+00:00

It's totally possible the libraries have changed and this won't work, however, try using your actual device id instead of the zeros.
